Tie Dan wielded his sword, and he had to strike with it.
After all, the three of them were in a state of dynamic balance at this time. The Sword Ball, hurricane, and Sun were tearing at each other. If left unchecked, it would only result in mutual destruction or demonic transformation. Even if that Black and White Pieces managed to emerge victorious, it would likely be in a state of great loss of Primordial Spirit, with a certain chance of becoming a brain-dead shell, rendering such a good Dao Body useless. Ignoring it would be the worst outcome.
And only Tie Dan possessed the ability and qualification to intervene, as he alone was proficient in Qi Manipulation, God Control, and Body Control, able to mend the rifts and conflicts of the three, calming the spirit and guiding the Refining to turn danger into safety, achieving peace in heart and body for a secure reincarnation. This is the crucial role of a master supporting his disciple.
